[SRU] [OEM-OSP1-B][PULL] drm/i915: Improve Ice Lake support

[Timo Aaltonen]

BugLink: http://bugs.launchpad.net/bugs/1825940

[Impact]
Add new backports from 5.2 and drm-intel-next.

[Test case]
The usual desktop usage, graphics tests etc.

[Regression potential]
Linux-oem-osp1 kernel is a new kernel used only on new OEM enablements, and it can't regress any currently running system.
